http://www.wordle.net/create is another word cloud program. The word cloud created reflected much of the same frequently words, but could not be saved as a jpeg file. This one is a simple program that allows you to print the word cloud and save it to a public site but you can't create a picture of the final product to save digitally.
The last word cloud program that is available is http://voyant-tools.org/. This program will be the program that I will use for the rest of research into several sets of WWI letter collections.
